Nervous Components
Central Nervous System (CNS): Comprises the brain and spinal cord.
Sensory neurones carry electrical impulses from receptors to the CNS.
Motor neurones carry electrical impulses from the CNS to effectors (muscles/glands).
Information from receptors passes along neurones as electrical impulses.
Always distinguish between a receptor (detects change) and an effector (carries out response).
